One of the equation of ellipse is in a form of the lengths of its axes. If we have the length of its major axis as 2a and the length of its minor axis as 2b then, the values of a and b are,
2a = 16, a = 16/2 = 8
2b = 4, b = 4/2 = 2
Given that we have the major axis as vertical, the equation for ellipse is,
y²/a² + x²/b² = 1
Substituting,
y²/8² + x²/2² = 1
Simplifying,
y² + 16x² = 1
<em>Answer: y² + 16x² = 1</em>
Yes because crosses through the origin. So it is considered proportional.
A) 5 feet
all the others are too long
I would say it is 4 because that is really the only one to make much sense <span />
Hello! So the original price is $120. It has a discount rate of 20%. You still pay 80% of the price, because 100 - 20 is 80. When we are looking for the sale price after the discount, we always mulitply the original amount by the percent of the price left to pay, after subtracting the discount from 100%. All we have to do is multiply 120 by 80% (0.8). 120 * 0.8 is 96. There. The sale price is $96. The answer is D: $96.
